Code extraction service contract
In applications developed based on the SpringMVC/POJO/JAX-RS model, one-click generation of service contract files conforming to the OpenAPI specification.
Service contract generation microservice project
Enter a service contract that conforms to the OpenAPI specification, one-click generation of a microservice project with ServiceComb/SpringCloud/Swagger as the base microservice framework and SpringMVC/POJO/JAX-RS or SpringBoot as programming model.
Service contract and code consistency check
Verify that the actual implementation of the application (such as the data and service API) is consistent with the agreed service contract description.
Service contract style checking and compatibility checking
The style checking checks whether the contract conforms to [OAS 3.0.2 specification] [openapi-3.0.2] and custom rules; the compatibility checking checks whether new OAS spec compatible with old spec
Service contract/code generation document
Enter a service contract that conforms to the OpenAPI specification, one-click generation of a document in html format.
Todo List
Support gradle plugin, eclipse plugin, intellij plugin.
Support for generating popular format documents such as word, pdf.
Support contract incremental generation code.
Make capability as a service.
Server-side automatic / semi-automatic test
Interface matching check
Support for generating microservice scaffolding containing code snippets that connect to common DBs such as Mysql / Redis
For users who integrate multi-vendor applications
Scene: the development languages, habits, and frameworks of different vendors are different, the entire system data and service standards are inconsistent, users are difficult to integrate, and it is difficult to manage and control the final delivery quality.
Solution:Through a uniformly defined interface description standard (service contract), a toolkit is used to generate a microservice project based on a specified microservices framework, and the consistency of the whole system is coordinated through service contract verification. Coordinate multiple development teams to reduce communication costs and avoid post-chaos.
For users who have evolved from legacy systems to microservices
Scene: additional learning and understanding of the microservices-related framework details is required before the microservices project can be designed, built, and developed according to the selected microservices framework. For users, Need to be distracted to focus on things outside the business.
Solution: Using the toolkit to analyze the legacy application extraction service contract, and then generate the microservices project based on the specified microservices framework, you can focus on business development and reduce the learning cost of the microservices framework.

When generating contracts from code,support for identifying restful interfaces written by the following annotations (class level)
RestController, RestSchema, RpcSchema, RequestMapping
When generating contracts from code,the restful interface method access modifier must be specified as public
